A consumer advocacy group says that three million Jeep Grand Cherokees have a potential fire danger from their gas tanks which is so high that the National Highway Traffic Safety Administration should order a recall.

Grand Cherokees from the 1993 through 2004 model years have “a fatal crash-fire occurrence rate that is about four times higher than S.U.V.’s made by other companies,” Clarence Ditlow, the executive director of the Center for Auto Safety, wrote in the request to the federal highway safety administration.
